Description

Preparation method of fuel cell cathode catalyst material
Technical Field
The invention relates to a preparation method of a fuel cell cathode catalyst material, in particular to a carbon-based transition metal doped s-C3N4A method for preparing a particle composite material.
Background
Generally, the energy conversion rate of the fuel cell can reach 40-60%, and the fuel cell has a relatively high energy conversion rate. Meanwhile, the fuel cell has no moving part, so that the fuel cell is quite quiet and does not generate noise in the operation process; furthermore, there is also little emission of atmospheric pollutants throughout the operation, for example, when hydrogen is used as a fuel, the only product is water. Therefore, the fuel cell is a high-efficiency and environment-friendly sustainable energy device. The most obstacle to large-scale commercial application of fuel cells is the cost problem caused by using noble metals such as Pt as catalysts, so research and development of non-noble metal cathode catalysts with wide raw material sources, low cost and high ORR catalytic activity to replace noble metal catalysts is the most key technology for reducing the cost of fuel cells and promoting large-scale commercial application of fuel cells.
In recent years, carbon materials have been studied because of their low cost, wide sources of raw materials, and simple synthesis processes. Carbon nitride is a novel carbon material with a unique two-dimensional structure, excellent chemical stability and tunable electronic structure. It plays a key role in the aspects of photodegradation of organic pollutants, hydrogen evolution in water, fluorescent probe detection, biological imaging and the like. Various heteroatoms are doped in the carbon nanostructure to modify the electronic structure of the carbon material, thereby changing the inert carbon into an active catalyst for ORR.
Graphene oxide is a very ideal electrocatalyst support material due to its small size, large surface area, low density, high electrical conductivity and thermal conductivity. This patent uses graphene oxide and s-C3N4As a carbon carrier, the method develops a new carbon-based electrocatalyst synthesis method by taking the design and preparation of an economic, efficient and stable oxygen reduction catalyst as a main research target. Due to Fe, Co and s-C3N4Strong coupling and synergy between @ rGO, Fe/Co @ rGO @ s-C3N4The composite material shows excellent catalytic activity and stability to ORR.
